A pressure washer is a powerful tool designed to make cleaning large surfaces quick and efficient. Whether you’re using it to clean your driveway, car, or siding, the pump inside the pressure washer plays a crucial role in generating the high-pressure water stream necessary for these tasks. However, just like any other mechanical device, the pump can accumulate debris, dirt, and mineral buildup over time. Proper maintenance of the pump is vital to ensure that your pressure washer continues to perform optimally.

Additionally, neglecting to clean the pump regularly can shorten the lifespan of your pressure washer, leading to costly repairs or replacement.
Furthermore, a clean pump ensures that the pressure washer operates smoothly and efficiently, maintaining its peak performance. Regular maintenance can prevent common issues like overheating or failure to start. By following the cleaning process outlined below, you can avoid these problems and extend the life of your machine.
Tools and Materials You Will Need
Before starting the cleaning process, gather the following tools and materials. You don’t need anything too complicated, just a few basic items to get the job done effectively:
Clean water: It’s crucial to use clean water to flush out the pump and remove any debris.
Pump cleaning solution: You can purchase a pressure washer pump cleaner or use a homemade solution of vinegar and water to help remove mineral deposits and buildup.
Soft cloth or sponge: This will help you wipe down the external parts of the pump.
A small brush: A soft-bristled brush, such as an old toothbrush, can help you scrub away any stubborn debris.
A hose: To connect your pump to a water supply for flushing it out.
Gloves: Protective gloves are a good idea to keep your hands safe, especially when dealing with chemicals or debris.
Once you have these tools, you’re ready to begin the cleaning process.
Step-by-Step Guide to Cleaning the Pressure Washer Pump
Step 1: Turn Off the Pressure Washer and Disconnect the Power Supply
The first step in cleaning a pressure washer’s pump is to turn off the machine and disconnect it from the power supply. If you are using an electric pressure washer, unplug it from the electrical outlet. If you’re using a gas-powered pressure washer, turn off the engine and disconnect the fuel line if needed.
Always make sure the machine is powered off and cool to the touch before beginning any maintenance tasks. This ensures your safety and prevents accidents from occurring while you work on the machine.
Step 2: Disconnect the Hose and Spray Wand
After the power is turned off, you need to disconnect the hose and spray wand from the pressure washer. This is important to ensure that no water flows through the system while you’re cleaning the pump. Removing these components will give you access to the pump itself and prevent any water from splashing while you’re working.
Step 3: Remove the Pump From the Pressure Washer
In some models, the pump is easy to access, and you may only need to wipe it down and clean it. However, in other models, the pump might be located inside a housing or behind a cover. If this is the case, you will need to remove the housing or cover to access the pump. Consult the owner’s manual for specific instructions on how to remove the pump housing in your model.
In most cases, the pump can be removed by unscrewing a few bolts or screws. Once the pump is exposed, you can begin the cleaning process.
Step 4: Flush the Pump With Clean Water
One of the first and simplest steps in cleaning a pressure washer pump is to flush it with clean water. To do this, connect a hose to the pump’s inlet and turn on the water supply. Allow the water to flow through the pump for several minutes. This will help clear out any loose debris, dirt, or other contaminants that may have accumulated inside the pump.
Flushing the pump with clean water is an effective way to get rid of larger particles before using any cleaning solution. It also helps ensure that the pump’s internal components are rinsed thoroughly, preventing any buildup from clogging the system.
Step 5: Use a Pump Cleaning Solution
After flushing the pump with clean water, it’s time to apply a pump cleaning solution. You can purchase a specific cleaning solution designed for pressure washers, or you can use a homemade solution made from equal parts water and white vinegar. The acidity in vinegar helps to break down mineral deposits, scale, and rust that may have built up inside the pump over time.
To apply the solution, pour it into the pump’s inlet using a funnel. Once the solution is inside, let it sit for 10 to 15 minutes. This will allow the solution to break down the buildup inside the pump. Make sure you follow the instructions provided with the cleaning solution if you’re using a commercial product.
Step 6: Scrub the Pump
After the cleaning solution has had time to sit, use a soft-bristled brush, such as an old toothbrush, to scrub the pump’s components. Focus on areas where mineral buildup or debris may have accumulated, such as the inlet, valves, and seals. Be gentle when scrubbing to avoid damaging any internal parts of the pump.
If your pump has a removable filter or screen, be sure to clean that thoroughly as well. These filters can often accumulate debris, which can restrict water flow if not cleaned regularly.
Step 7: Rinse the Pump Thoroughly
Once you have scrubbed the pump and removed any visible debris, it’s time to rinse it thoroughly. Use clean water to flush out the pump and remove the cleaning solution. Make sure that all the cleaning solution has been flushed out of the system before proceeding.
Rinsing the pump properly is essential because any leftover cleaning solution could interfere with the performance of the pressure washer. If there’s any vinegar left inside, it could also cause damage to the pump’s seals or other components over time.
Step 8: Inspect the Pump for Any Damage
While the pump is exposed, take this opportunity to inspect it for any signs of damage. Look for cracks, leaks, or any worn-out components. If you notice any issues, it may be time to replace parts of the pump or the entire unit. Early detection of problems can prevent further damage and costly repairs in the future.
Step 9: Reassemble the Pressure Washer
After thoroughly cleaning and inspecting the pump, it’s time to reassemble your pressure washer. If you had to remove the pump or any housing, replace those components and secure them with screws or bolts. Once everything is reassembled, connect the hose and spray wand back to the pressure washer.
Ensure that all connections are tight and secure before turning the pressure washer back on.
Step 10: Test the Pressure Washer
Before using your pressure washer for your next cleaning task, it’s a good idea to run it through a test. Turn on the power and let the machine run for a few minutes to ensure that the pump is functioning properly. Check for any unusual sounds, leaks, or loss of pressure. If the pump is working correctly, you should notice consistent water flow and high pressure.
If there are any issues during the test, consult the user manual or contact a professional for further assistance.
Tips for Maintaining the Pressure Washer Pump
Cleaning your pressure washer’s pump is just one part of keeping it in top condition. Regular maintenance can help prevent buildup and extend the life of the pump. Here are some additional tips to keep your pump running smoothly:
